All SCSI direct-access CAM devices are required to support it. You say 30Meg: I didn't know Seagate made a 30Meg SCSI drive. If they do, it may be an _old_ drive (like the 225N's: barely compliant). >THE PROBLEM WHEN THE POWER IS TURNED OFF!

The problem is that Seagate drives (especially old ones) take forever to spin up, up to 30 seconds. There's a soft switch in the NVRAM in the A3000 for setting "seagate mode", but there's no prefs editor for it yet. The A2091 and A590 have dip switches/jumpers for this. The solution (until the editor appears): after power-up, wait a few seconds and warm-boot. -- Randell Jesup, Keeper of AmigaDos, Commodore Engineering. {uunet|rutgers}!cbmvax!jesup, jesup@cbmvax.cbm.commodore.com BIX: rjesup Common phrase heard at Amiga Devcon '89: "It's in there!"
